The present invention relates to bow sights and more particularly to a new compound bow rifle sight system which eliminates the need for a peep sight on a bow. The sight aids the archer in maintaining a consistent body form for accuracy which is crucial to the archer. The sight of the invention is designed to be used in conjunction with a front mounted sight, such as a pin sight, which is used in aiming of a bow and an arrow to be fired by the bow at a target.
The use of various bow sighting and aiming systems is generally known in the prior art, as evidenced by the sighting systems disclosed in U.S. Pat. Nos. 5,303,479; 4,620,372; 5,048,193; 5,802,726; 6,026,799 and U.S. Des. Pat. No. 423,627.
Known sight devices, such as pin sights, are mounted forward of the bow and away from the user of the bow when the bow is being held in use by an archer. The known pin sights require a peep sight that is mounted in the bow string to the rear of the bow so that the peep sight is carried by the string and is generally positioned between the pin sight and the user. The combination of the bow mounted pin sight and the string mounted peep sight is intended to produce an accurate aiming of the arrow toward the distant target. In use of the prior art the archer draws back the string of the bow to a set point that the archer is comfortable with, the peep sight should then be close to the eye of the archer and oriented so that the pin sights are visible through a hole in the peep sight. A string line fixed to the bow is often used to properly orient the peep sight.
The use of a peep sight with or without a pin sight has a number of drawbacks. The movable peep sight defines a small hole for the archer to peer through in aligning a shot. One problem with peep sights is that the material surrounding the peep sight hole will obscure the view of the archer. The peep sights commonly in use give the archer about a 10 degree diameter field of view, anything outside this circle of view is obscured. In low light conditions it can be difficult to locate a target through the peep sight. Because the peep sight is so close to the archer's eye it is not possible to see any peep sight structure that would aid the archer in alignment, the archer's eye is focused at 10 to 40 yards where the target is. So instead of having something like cross hairs to align with the correct pin, the archer just has 3 or 4 pins floating in a hazily defined 10 degree circle. The archer then attempts to center a pin in the 10 degree circle with the pin over the target. Good archers do this successfully but it takes time to acquire the target and any bow hunter will tell about the buck that got away while the archer was attempting to ‘get a bead’ on the target buck. It is also very easy to get a pin on a target and miss the shot because of misalignment of the archer's head and eye relative to the peep sight or because the bow, bow string or peep sight are misaligned. Commonly, the archers eye can be left, right, high or below the center of the peep sight, the archer can sight in the bow with a pin on the target but the shot for example will go left because the archer's eye is slightly right of center of the peep.
As can be seen there is a need for a bow sight that will not have all the problems associated with the prior art. Specifically there is a need for an improved bow sight that will eliminate the alignment and field of view problems associated with the peep sight.
In view of the foregoing disadvantages inherent in the known types of bow sights now present in the prior art, the present invention provides a new compound bow rifle sight system for replacing the string mounted peep sight on the bow.
The present invention is a bow sight system that includes a bow sight assembly comprising a base plate with a longitudinal axis for mounting on the bow, and a sight assembly having a sight groove which is preferably a V-shaped notch. The sight assembly is mounted on the base plate so that the sighting assembly is adjustably movable along an axis that is substantially perpendicular to the base plate to adjust the position of the sight groove of the sighting assembly in a horizontal direction, and is adjustably movable in a plane that is substantially perpendicular to the longitudinal axis of the base plate to adjust the sight groove in a vertical direction. The system may include a pin sight assembly mounted in a position forward of the bow.
There has been thus outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will from the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
It is an object of the present invention to provide a new compound bow rifle sight system for aiding in the aiming of a bow.
It is a further object of the present invention to provide a compound bow sight that will correct bow torque and misalignment and allow the archer to maintain the same consistent body form time after time, which is crucial in accurate aiming of the bow.
Yet another object of the present invention is to provide a new compound bow rifle sight system which includes a bow sight assembly comprising a base plate with a longitudinal axis for mounting on the bow, and a sighting assembly having a sight groove which can be a V-shaped notch. The sighting assembly is mounted on the base plate so that the sighting assembly is adjustably movable along an axis that is substantially perpendicular to the base plate to adjust the position of the sight groove in a horizontal direction and is mounted on the base plate so that the sighting assembly can be adjustably movable in a plane that is oriented substantially perpendicular to the longitudinal axis of the base plate to adjust the position of the sighting assembly in a vertical direction. The system may include a bow and the bow sight assembly is mounted in a position rearward of the bow. The system may include a pin sight assembly mounted in a position forward of the bow.
Still yet another object of the present invention is to provide a new compound bow rifle sight system that can be retrofit to an existing bow to replace the peep sight previously used thereon and which may be used in combination with virtually any type of forward mounted sight assembly including pin sights.
Yet another object of the present invention is to provide a new compound bow rifle sight system using an adjustably sighting groove and a pin sight in combination. The system providing a thickness of the sighting V groove such that a misalignment of the archer or bow will cause the sighting groove to obscure the pin from view thus preventing an errant shot.
It is still another object of the present invention to provide a sighting groove that will provide a wide field of view while also providing the archer with reference points including a groove and alignment points to allow for accurate repeatable aiming of the bow. While providing a wide field of view the present invention does obscure unused pins to provide a less cluttered field of view for the archer allowing a more rapid acquisition of the target.
It is also an object of the present invention to provide a targeting system that will obscure unused pins while at the same time providing an indication of target distance by the number of pins that are visible.
These and other objects of the present invention will become more clear in the following detailed description of the invention with reference to the drawings.
Referring now to
In a first embodiment of the invention, illustrated in
A second plate 30 can have a first side 32, a second side 34, a top edge 36, a bottom edge 38, a first side edge 40 and a second side edge 42. The second plate 30 has a ninety-degree bend 44 therein extending between the top edge 36 and the bottom edge 38 and positioned nearer the second side edge 42 than the first side edge 40 of the second plate 30. The second side edge 42 of the second plate 30 is integrally formed with the first edge 22 of the first plate 12 at a generally perpendicular angle such that the first plate 12 lies in a plane oriented generally parallel to a plane of the second plate 30. The first plate 12 extends in an opposite direction to the second plate 30. A pair of apertures 46 extend through the second plate 30. The apertures 46 are spaced from one another. Each of the aperture 46 is elongated in a direction perpendicular to an axis through slot 26. Fasteners (not shown) can extend through apertures 46 to secure the bow sight system 10 to a bow 2 which commonly have threaded holes corresponding to the spacing of apertures 46. The elongated nature of the apertures 46 allows the device to be selectively moved on the bow 2 to optimize the distance of a sight 50 from the pins sight assembly 1 while preventing interference with the bow string 3. The aperture 46 will also allow for differences in hole spacing on different bows 2 to which the system 10 might be retrofit.
A sight 50 is positioned in and movable along the elongated slot 26. The sight 50 can comprise an elongated threaded member 52 having a first end 54 and a second end 56. The elongated member 52 can extend through the slot 26. A pair of securing members 58 are threadably coupled to the elongated member 52 for removably securing the elongated member 52 to the first plate 12. The first plate 12 is secured between the securing members 58 each of which can be a nut. A disc 60 is attached to the first end 54 of the elongated member 52. The disc lies in a plane oriented perpendicular to the plane of the first plate and perpendicular to a fine defining the direction of arrow flight to a target not shown. The disc 60 has an edge with a V-shaped groove 62 therein. Alternatively, the disc 60 may have a rectangular shape, or other geometrical shapes in place of the round shape. Of importance is the V-shaped groove 62 which is used for sighting purposes.
A second embodiment is shown in
The support portion 82 may comprise a neck portion 90 and an adjustment section 92. The neck section 92 of the support portion may be mounted on the mounting portion 80, and the neck section 92 may extend outwardly from the mounting portion 80. The adjustment section 92 may be oriented substantially transverse to a longitudinal axis of the neck section 90. The support portion 82 may include a support slot 94, which may be located on the adjustment section 92. The support slot 94 may be oriented substantially perpendicular to the first 84 and second 86 mounting slots.
The sighting assembly 74 may guide the aiming of the bow 3 by eye of the user of the invention such as by correcting the body alignment with the bow 3. The sighting assembly 74 may be mounted on the base plate 72 in a manner that permits adjustable movement of the sighting assembly 74 on the base plate 72. The sighting assembly 74 may be adjustably movable on and with respect to the base plate 72 in directions that are perpendicular to the longitudinal axis of the base plate 72. The sighting assembly 74 may also be movable in a plane that is oriented perpendicular to the longitudinal axis of the base plate to permit adjustment of the orientation of the sight in a vertical direction when the invention is mounted on a bow 3.
The sighting assembly 74 may include a pedestal 96 that is slidably mounted on the base plate 72. The pedestal 96 may have a channel 98 formed therein, and the channel 98 may extend substantially perpendicular to a plane defined by the base plate 72. A set screw set hole 100 may be formed in the pedestal 96 and may be in communication with the channel 98, and a set screw 102 may be positioned in the set screw hole 100 such that rotation of the set screw 102 in a first direction moves the set screw 102 inwardly with respect to the pedestal 96.
The pedestal 96 may include an anchor member 104 that is positioned adjacent to the base plate 72. The channel 98 may be formed in the anchor member 104 in a location that is opposite of the base plate 72. The pedestal 96 may also include a backing plate 106 that is positioned on a side of the base plate 72 at a location that is opposite of the anchor member 104. The pedestal 96 may also include at least one fastener, and preferably includes a pair of fasteners 108, 109. The channel 98 may extend through the anchor member 104 and through the backing plate 106.
The sighting assembly 74 may also include a mast member 110 that is mounted on the pedestal 96. An end portion of the mast member 110 may be positioned in the channel 98 of the pedestal 96. A position of the mast member 110 in the channel 98 may be adjustable along an axis that extends substantially perpendicular to the plane of the base plate 72. The set screw 102 may be selectively abbuttable against the end portion of the mast member 110 that is positioned in the channel 98 for securing a position of the mast member 110 with respect to the pedestal 96.
The sighting assembly 74 may also include a sight guide 112 that is mounted on the mast member 110, and the sight guide may have a top 114 for orienting upwardly and a bottom 115 for orienting downwardly when the invention is mounted on a bow 3. The sight guide 112 may include a sight groove 116 that is formed therein, and the sight groove may have a substantial V-shaped cross section to form a V shaped notch. The sight groove 116 may extend from the top 114 of the sight guide 112 toward the bottom 115 of the sight guide 112. The thickness of the sight groove, from front to back should be sufficient to assure that the user's view through the groove is substantially parallel to the plane of the support portion of the base plate 72. If the bow 3 is turned relative to the user about a vertical axis, the user will not be able to see the pin of the pin sight 1. (See
The sight guide 112 may also include a pair of alignment marks 118, 119 that are marked on the sight guide 112. Each alignment mark 118, 119 may comprise a dot and the dots may be located on opposite sides of the sight groove 116. The alignment dots 118, 119 may be located adjacent to the top 114 of the sight guide 112 and can be painted with highly reflective or florescent paint or the alignment dots 118, 119 can be lighted fiber optics to aid the user in seeing them even in low light conditions.
The first bracket portion 122 may be positioned adjacent to the base plate 72 and the second bracket portion 124 may extend from the first bracket portion 122. The second bracket portion 124 includes a light 126. The light 126 can be battery powered and can operate at a frequency that will not distract the archer and yet one that will cause the alignment marks 118, 119 to glow visibly.
In use, the device is generally used in conjunction with a sight mounted forwardly on the bow 2 such as pin sight 1. The bow sight assembly of the present invention is attached to a bow 2 in a position rearward of the bow 2 toward the user. The sight is positioned and adjusted to suit the archer and the characteristics of the bow such as size and poundage of draw. The archer then lines up the V groove 116 of the sight assembly 74 with the appropriate pin 209 as shown in
